“Going into the reunion, I’m always a little nervous,” she explains, adding that she didn’t sleep at all the night before. “You’re feeling like, Oh my God, what’s going to happen? What are they going to pull out of their ass to make this reunion powerful?”

Vicki goes on to say that, regardless of her nerves, she arrived ready to go to battle. “I had a whole folder of stuff, and if they were coming at me, I was prepared! I spent some time trying to figure out why Lauri was doing what she was doing, so I had my facts ready.”

Unfortunately, the uncertainty of the day did get the best of the OG of the OC. “Getting ready to get on set, I vomited three times. I didn’t even have any food in my stomach, I was just so nervous.”

At the end of the day, Vicki’s a pro when it comes to these reunions, and she knows how to handle herself in style. “It was 12 hours of hell, [but] I survived it!”
